Check for changing surface conditions as you travel

Small, wet avalanches become more likely as the surface crust breaks down. Continue to give cornices space, they may be weak and unstable.




Avalanche Summary

No new avalanches have been reported in the last 2 days. We expect wet avalanches may occur on sun affected slopes with strong sunshine and warm temperatures on Friday. North-facing alpine slopes still hold dry snow, reactivity may affected in wind affected pockets here.

If you have any recent photos or observations, please submit them to the Mountain Information Network, observations are limited in the spring.

Snowpack Summary

A widespread surface crust likely exists at all elevations, except on high north-facing slopes where pockets of wind affected dry snow exist above 2000 m. Watch for moist, unstable snow on southerly slopes with sun and warm temperatures.

Below treeline terrain has low snow cover. Travel conditions are challenging with exposed rocks, stumps, and open creeks.
